Hi,

standard_ExplainOneQuery()I had to copy the code and create my own version.

standard_WhateverFunction()for each WhateverFunction_hook, I created a patch to follow this pattern for your
consideration.

thatwould be useful to the community.
Thanks for the patch. LGTM.
I registered the patch on the nearest open CF [1] and marked it as
RfC. It is a pretty straightforward refactoring.
